Hundreds of messages of support have been posted on a social media website for a four-year-old girl from Kent who fell several feet from a walkway at a theme park. Jessica Blake, from Sheerness on the Isle of Sheppey, remains in a critical condition in hospital.

She suffered a fractured skull, and a bleed on the brain and broken ribs, after falling from the Tomb Blaster ride queue at Chessington World of Adventure in Surrey on Thursday. The theme park said an internal investigation was underway and the Health and Safety Executive had been informed.

"The resort's fully-trained medical staff were on site immediately and administered direct care to the child until ambulance teams arrived.

"She was then taken to hospital in a conscious state. Until all investigations have concluded we are not in a position to comment further.
